Default Does a cutout effect tune?

Hey guys,

I have a cutout on my Z, but my car was tuned with the cutout closed. Is it possible that opening the cutout and running it that way on a daily basis would not "mix" with the way the car was tuned via closed cutout, and perhaps throw codes because of it?

example: P0172 and P0175 (Banks 1 and 2 rich)

no if anything it should be leaner with it open. shouldnt be nothing to worry about unless you are hitting it with spray or fi. the computer will adjust for the most part.

As long as your cutout is at least a few feet after your 02 sensors you should be ok.
